4.5 litre tub home washing powder (Bath BA2)

4.5 litres of an airtight tub of homemade washing powder. I made far too much this year; it is of equal parts
Borac
stain remover
washing soda crystals and
grated soap/
! tablespoon for 1 wash, so it should last more than 6 months of heavy use,
It does not soap up, so don't add more to see suds. This type of powder does not soap up It works a bit like the laundry eco egg.
To go as soon as possible.
